7. Parts of a microscope Eyepiece Nosepiece Arm Stage Diaphragm Base

8. Parts of a microscope: Eyepiece -Magnifies the object 10x -Can be 1 or 2 eyepieces present

9. Parts of a microscope: Nosepiece Objective lenses (4x, 10x, 40x) -Holds the lenses

10. Parts of a microscope: Stage elements Stage Clips—holds the slide in place Diaphragm—controls the amount of light

11. Parts of a microscope: Power, light, and focus Coarse Adjustment-used to focus, moves the slide a lot Fine Adjustment—used to focus, moves the slide a little Light—shines through the specimen so it is visible Power switch—turns the light on

12. Magnification and resolution Magnification is the enlargement of a specimen. To determine magnification you take: power of the eyepiece X the power of the objective  Example: A 10X eyepiece and a 4X objective magnifies the specimen 40X.

13. How to see a slide Put on low power Put slide on stage/center Coarse focus Fine focus Light adjustments
